采用投加高效微生物菌剂的方式处理食堂污水,考察微生物菌剂用于城镇污水分散式处理的可行性.结果表明,微生物菌剂对食堂污水的处理效果显著,当原水COD、NH_4~+-N、TN和TP浓度分别为(255～460)、(11.69～18.62)、(14.7～24.6)、(2～5.5) mg/L时,运行50 d后,二级生物强化池的出水COD、NH_4~+-N、TN和TP浓度分别稳定在50、5.0、5.0、1.0 mg/L以下,达到了<城镇污水处理厂污染物排放标准>(GB 18918-2002)的一级A标准;再经生态修复处理后,水质得到进一步改善,可达到<地表水环境质量标准>(GB 3838-2002)的Ⅳ类标准.与传统活性污泥法相比,该技术的投资费用降低了50%以上,运行维护费用降低了30%以上,为城镇污水分散式处理技术提供了一种新思路.

Canteen wastewater was treated by adding highly efficient microbial agent, and the feasibility of decentralized treatment of municipal wastewater by the microbial agent was investigated. The results show that the treatment efficiency of the canteen wastewater by the microbial agent is significant. When the influent concentrations of COD, NH_4~+-N, TN and TP are 255 to 460 mg/L, 11.69 to 18.62 mg/L, 14.7 to 24.6 mg/L and 2 to 5.5 mg/L respectively, the effluent concentrations of COD, NH_4~+-N, TN and TP in the secondary bioaugmentation tank are less than 50 mg/L, 5.0 mg/L, 5.0 mg/L and 1.0 mg/L respectively after operation for 50 d, which reach the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). After further treatment of ecological remediation, the quality of treated water is improved and can reach class Ⅳ specified in Environmental Quality Standards for Surface Water (GB 3838-2002). Compared with the traditional activated sludge process, the investment cost and operation cost of this process are reduced by more than 50% and 30%, providing a new way for decentralized treatment of municipal wastewater.
